Xara Xtreme has always had by far the highest performing graphics rendering engine, up to ten times faster than Adobe Illustrator. V4 introduced support for multi-core processors in Xara Xtreme Pro making it even faster than before! Tests show approximate speed gains of 40% for a dual core processor with large screen images, and greater gains with more cores. Large full screen photos can render up to 75% faster on a dual core processor.
